LayerOne 2015 Dual Electronic Badges

PSoC4 blinky badge and VoCore OpenWRT network badge

LayerOne 2015's badge effort produced two electronic badge designs documented by the official Hardware Hacking Village archive and CharlieX's Hackaday.io project: a battery-powered PSoC4, ESP8266, and WS2812B blinky badge plus a VoCore/RT5350F OpenWRT network badge with Wi-Fi and dual Ethernet intent.

Why It Mattered

It captures a LayerOne year where badgelife split into two hackable surfaces at once: a visible addressable-LED badge for attendee light effects and wireless experiments, and a compact Linux/OpenWRT network badge for security-conference hacking workflows.

Hardware

The Hackaday.io project describes the blinky badge as a 3.3 V PSoC4 design with ESP8266 Wi-Fi, WS2812B LEDs, I/O ports, 3 V to 5 V level-shifting work, diode reverse-polarity protection, two CR123A cells, daisy-chain behavior, and pick-and-place assembly. The second badge is documented around a VoCore module with RT5350F, OpenWRT, Wi-Fi, two Ethernet ports, USB host/storage goals, microSD and mini-USB supporting parts, and heatsink work.

Software & Apps

The project says PSoC LED routines were back-ported from a PC lightserver and kept a UDP drive path for sending patterns or RGB blocks from another Wi-Fi device. The VoCore side documents OpenWRT buildroot setup, RT5350/VoCore menuconfig, LuCI, USB storage modules, sysupgrade flashing, first-login/telnet setup, SSH/telnet administration, opkg package work, and BusyBox/OpenWRT basics.

Lore

LayerOne's HHV archive names the 2015 Electronic Badge and links CharlieX's Hackaday.io build details for both badges. Build logs say kits were made, speaker and staff badges were built, LED badges were being assembled with a TM-220A pick-and-place, and the boards were chainable; earlier logs preserve prototype mistakes, VoCore USB mirroring, level-shifter changes, and final-manufacturing pressure.

PSoC4 ESP8266 LED badge

The Hackaday.io project describes a battery-powered blinky badge using PSoC4, ESP8266 Wi-Fi, WS2812B LEDs, I/O ports, and 3.3 V logic with LED level-shifting work.

UDP RGB drive path

The project details say PSoC routines were back-ported from a PC lightserver and left able to receive patterns or blocks of RGB values over UDP from another Wi-Fi device.

Issues & Camp Impact

dual-badge consolidation caveat note

The official HHV archive and Hackaday.io project describe two 2015 badges, so this catalogue keeps them in one LayerOne 2015 record while clearly separating the PSoC4/ESP8266 LED badge from the VoCore/OpenWRT network badge.

Readers see the two-source-backed badge designs without treating one board's hardware, firmware, or production state as universal to the other.

Confidence: official archive and project logs
Status: documented with caution
Timeframe: LayerOne 2015
Source note: LayerOne HHV 2015 Electronic Badge section and CharlieX Hackaday.io project.

missing rights-cleared image note

No LayerOne 2015 Dual Electronic Badges image is published because the current public source trail has not been paired with a reusable original badge or artifact photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The United States record remains source-backed and image-free rather than copying source-page media, documentation screenshots, event photos, social media, placeholders, or generated approximations.

Confidence: local project policy
Status: needs licensed original replacement
Timeframe: current catalogue build
Source note: badge.gallery image policy and LayerOne 2015 HHV, InfoconDB, Hackaday.io, and charlie-x repository source trail.

prototype-to-production caveat note

The public Hackaday.io material mixes prototypes, late board changes, USB mirroring, level-shifter selection, build pressure, and final assembly notes rather than a single audited final production package.

The catalogue records the source-backed architecture and build status while avoiding unsupported claims about every final shipped component, firmware image, quantity, or attendee role.

Confidence: badge-team logs
Status: documented with caution
Timeframe: 2015 badge development
